-B'e it known that I, JOSEPH H. KING, a

citizen of the United States, residing at .ESan Diego, in the county'of San'Diego and "State of California. have invented a certain new 'anduseful Grindstone, of which the following is'a s ecification. My inventlonrelates togrindstones, more particularly to that class of grindstones in which aportion of the grinding memberis adapted to be'positioned in water or other liquid while in operation. 7. I It has been c ustomary in the past to provide" a .grindstone. with troughs or pans partly filled with water in which the stone stood at all times until the water was used or emptied out. By this means the portion o'fthe'grindstone standing in the water was subjected to disintegration and softened so that whenfthestone was used for grinding the portion thus disintegrated or softened grinding surfacee ccentric and very irregular. and useless for fine work.

he objects of this. invention arei: F irst,

to provide a grindstone of this class in which a trough, partly .filled' with water or other liquid,is movably positioned at the lower po'rtion of thestone so that when the grindstone'is not' in use the trough may be lower'edfand when in use the trough'may be raised and the stonebe positioned in' the water'g second, to provide a grindstone of this class in which the trough will beautomatically positioned'so that-the liquid in the trough will surround a" portion ofthe stonewhen the same is in luse;third, to pro- "vide' an apparatus of this class forgrind- 'andwhich will not stones which can be very easily adjusted to accommodate; different sizes of grindstones and for positioning the stone in the liquid at different depths; fourth, to providea novelly "constructed and operated apparatus of this class, and fifth; to provide an apparatus of this class which is very simple and economi'c'al' of construction," durable; practical, which maybe; easily' installed on any grindstone, readily deteriorate or get out of order.

these and other objects in view, as w ll: appear hereinafter, my invention consists of certain novel features of constructibri, combination and arrangement of parts and portions as will be hereinafter described in detail 'and particularlysetjforth inl the appended c1ainis,reference being had to the accompanying drawings and to the "characters of reference thereon; which formia part OfthlS' application, in whi'chz Figure 1 is'a side elevatioriall viewbf my grindst'one,showingcertain hidden parts by dotted ."lines and "showingby otherdotte'd lines: the 'upwardlyshifted position-16f the trough and other corr'es'pondinglj' shifted parts; Fig. 2; is a plan view thereof ;*:Fig., '3

At the outer ends of said operating arms are secured the J-shapedseat supporting members 12 which support the seat 14, substantially as shown in the drawings. Itwill be noted thatthe ends of. the operating arms 9, connected to the Ill-shaped, trough supporting member 8, are turned inwardly and backwardly to receive theupper ends of the member 8- for supporting the same in alignment therewith and for loosely supporting the same therein to permit free pivotal movement of the member 8 saidmember 8 being provided at its upper ends with a plurality of holes 8* for adjnstably connecting said member with the operatingarms 9.. It will also be noted that the portions of the operating arms 9 forward of their pivotal mounting are separated sufiiciently to straddle the stone 2 and immediately behind their pivotal mounting are offset] inwardly and extend backwardly through a. slot 1 in the upper portion of the rear leg I ofthe supporting frame. To

7 the extreme rear end of the arms 9 are secured the shorternlegs. of the'J-shaped seat supporting members 12 by the rivets 13', the longer legs. of; which seat supporting memhers are extended outwardly and: downwardly straddling the. beams 1 of the supporting frame and are secured together near their lower ends by the bolt 16, which serves as a stop for the upper position of the seat or the lower position of the trough posi tion being regulated by the position of the bolt 16 which is adapted. totbe inserted in the. different holes 12E" in the longer le s of said. J' shapecl" seat. supporting mem ers.

The connecting, portion of the long and short legs of said J-shaped memloers 12 serve as a stopfor the lower position of the seat. and the upper position of the trough, and also the securing portion of the seat 14,

which is secured thereto by the bolts 15. zlhe conventional, channel-shaped guard 17 isprovided at the rear portion of the grindstone member 2 forthe support of the tools and protection against splashing of water. Though I have shown and described a particular construction, combinationand arrangementof partsand portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include 1n the scope of my 111- v-eufion, the construction, combination and arrangement substantially as set forth in the ap ended claims. r

H t is obvious from this construction that there is provided a grindstone apparatus in which the trough for wetting the grindstone member therein is movably mounted at the lower portion of said grindstone member; that the trough is automatically shifted in an upward position for wetting the grindstone member in the liquid provided therein whenthe operator is ready stone apparatus of this class which is very 1 simple and economical of construction, durable, efficient, applicable for different styles and sizes of grindstones', and which will not readily deteriorate or get out of order.

Having thus described my inventionflvhat I claim as new and tears Patent, is :v

1. An apparatus of the class described including a supporting frame, a grinding desire to secure by Letmember revolublylmounted thereon, a mani.

ual means for revolving saidgrinding member, a 'troughfor said grinding niembe'r, vertically shiftably positioned at the lower portion of the, grinding member, elem pivotally mounted on said supporting frame,

to the one end of which ispivotally connected the trough and a seat member supported at the opposite end. of said lever, upon which the operator sits for manually revolving said grinding member and for vertically Y shifting said trough when the operator gets off of said seat. v I

2. An apparatus of the class described including a supporting frame, a grinding member revolubly mounted thereon, a manual means for revolving said grinding memher, a trough for said grinding member, vertically shiftably positioned at the lower portion of the grinding member, lever means mounted on said supporting frame for raisi ing and lowering said trough, and a seat supported by said lever means for theoperator of said. apparatus, whereby the trough 'is automatically shifted upwardly or down werdlv by the movement of :said seatwhen the operator gets on and oitof said sea-t. 3. An apparatus of. the classdescribed including a supporting frame, a grindstone member revolubly mounted thereon, a

means for revolving said grindstone memher, a trough adapted to be partly filled with aliq'uid, positioned at'the lower portion of said grindstonemember and shiftable vertically therewith, a lever pivotally trough, when the operator gets 0n and ofi mounted on said sup orting frame, to the of said seat. one end of which is plvotally connected the In testimony whereof, I have hereunto 10 trough,,a stop means provided on said lever set my hand at San Diego, California, this for limiting the movement of said trough, 26th day of February, 1923. and a seat member supported atthe opposlte end of said lever for vertically shifting said p JOSEPH H.
